PIVOTED SASH- SPECIFICATION forming part of Letters Patent N0. 754,655, dated March 15, 1904.

k Application filed June 12, 1903. Serial No. 161,204. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE KABURECK, a citizen of the United States of America, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Pivoted Sashes, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The vobject of this invention is to provide a pivoted sash for use in windows of any construction, but which is more particularly designed for windows of the vertically-movablesash type and which is simple in construction and operation, positive in action, which'will not easily get out of order, and by means of which the glass in said sash may be readily cleaned on both sides from within, a further object being to provide sash of this class which is weatherproof and which prevents the rattling common to vertically-movablesash windows, a further object also being to provide a sash of the'class hereinafter described and claimed which automatically assumes a Vertical position when released and which also automatically adjusts itself to its normal position and without the use of screws, clamps, or similar devices.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which Figure 1 is an inside elevation of a windowframe constructed according to my invention; Fig. 2, a section on the line 2 2 of Fig. 1 and showing both sash in the same relative position and in different operative positions; Fig. 3, a section on the line 3 3 of Figs. 2 and 4; Fig. 4, a section on the line 4 4 of Figs. 2 and 3, and Fig. 5 a section on the line 5 5 of Fig. 2..

In the drawings forming part of this specification I have shown a window-frame a, provided with the usual sash-runs a and in the drawings the frame a is shown as of metal construction; but the same may be of wood or any other suitable material, as will be understood, and the frame a is provided with theusual weight-pockets a Slidably mounted in each of the sash-runs a is a weight-strip Z), which comprises a casing in which are secured a plurality of bowsprings 5 upon the ends of each of which are antifriction-rollers b and in practice the rollers 6 project beyond the casing 12 and bear upon the back (4 of the runs a and when the sash is in its normal position, as shown at of, Fig. 2, the weight-strip I) is forced away from the back (4* of the runs by the bow-springs 6 The casing of the weight-strips I) is curved on its inner side, as shown, and provided with a recessjlf, thereby forming two projections b and b, and the recess 6* and projections 6 and I) extend the full length of the weight-- stripsb, and secured within the casing of the weight-strip b and centrally-thereof, or nearly so, is a block 6 to the upper end of which is connected a rod 5 to which the usual chain or cord 6 is connected, said chain or cord being secured at its other end to the usual sashweights, said Weights not being shown.

Detachably secured in the center of the block b of each of the weight-strips Z) is a pivotbolt 0, which also passes into the side bar of a sash 0 said sash being provided with a recess 0 for this purpose, said recess being covered by a plate 0, detachably secured to the inner side of each of the sidebars of both of the sashes c and the plates 0* are each provided with a slot 0 through which passes the outer end of a lever (Z, the other end of'which is pivoted in the recess 0 as shown in Fig. 2 of the drawings, and the lever Z bears against the head 0 of the pivot-boltc.

The side bars of each of the sashes 0 are each provided on their edges adjacent to the weight-strips b, with which they engage, with a central longitudinal projection e and projections e on the edges thereof, thereby forming recesses e and the projections b and b of the weight-strips b normally rest in the recesses of the sashes c and the projection e of the sashes engages the recess 6* of the weight-strips b, and by means of this construction when the sashes are in their normal positions neither wind nor water can pass between the sashes and their corresponding weight-strips, and in practice I prefer to leave a space a between said sashes and weightstrips, the object of which is to prevent water from passing therethrough by capillary attraction.

\Vhcn it is desired to swing one of the sashes 0 upon its pivots, all that is necessary is to force the lever (Z, by means of the free outer end thereof, against the head 0 of the pivotbolt 0, and as the pivot-bolts are loosely mounted in the sashes c the lever d operates to force the weight-strips against the action of the bow-springs 71 and out of engagement with the sash, and said sash can then be swung the top inward and the bottom outward, and this operation may also be performed with the upper sash, as will be readily understood, and when the glass has been cleaned on the outer side the sash resumes its vertical position, for the reason that the sash-weights are connected with the sash at a point above the center and gravity brings the same into its vertical position, and when in this position the bowsprings 6 force the projections on the sash and corresponding weight-strips into engagement with the recesses therein and the sash is automatically locked.

When the sash are placed in position in the construction of the window, the weight-strips of the upper sash are placed in the corresponding runs, the sash-cords connected therewith, and sash-weights adjusted, after which the sash is sprung into position between the weight-strips, and the plates 0" not being in position at this time the pivot-bolts c are inserted through the recesses c and screwed or otherwise secured in the corresponding weight-strips, after which the levers (Z are placed in position and the plates 0 screwed on, the outer end of the levers (Z passing through the slots 0', which serve as guides therefor, and the sash is in operative position, and this operation being repeated with the lower sash the window is complete, and the sash have been connected and may be removed without in any way interfering with the parts of the window-frame.

As will be seen, my pivoted sash is simple in construction and operation and well adapted for the purpose for which it is intended, and various changes in and modifications of the construction herein shown and described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a window comprising a frame and the usual sash -runs formed therein, a sash, a weight-strip on each side of said sash and in operation therewith, a pivotbolt secured in each of said weight-strips and passing into said sash, a plurality of bow-springs on each of said weight-strips, a plurality of antifriction-rollers on each of said bow-springs and bearing against the backs of the corresponding sashruns and means for forcing said weight-strips against the action of said bow-springs and out of engagement with said sash, substantially as shown and described.

2. In a window comprising a frame and sashruns formed therein, a sash, a weight-strip on each side of said sash and in operative engagement therewith, a pivot-bolt in each of said weight-strips and passing into said sash, a .plurality of springs secured in said weightstrips, a plurality of antifriction-rollers on each of said springs, said antifriction-rollers being adapted to bear against the backs of the corresponding sash-runs, a lever pivoted in each side of said sash, adjacent to said pivotbolt and adapted to operate thereon, a plate detachably secured to the inner side of said sash and adjacent to said lever on either side of said sash, a slot in each of said plates through which the outer end of each of said levers passes and means for locking said sash to said weightstrips, substantially as shown and described.

3. In a window comprising a frame and the usual sash-runs formed therein, a sash, a weight-strip on either side thereof, a pivotbolt in each of said weight-strips and passing into said sash, a plurality of longitudinal projections on each side of said sash and forming recesses thereby, a plurality of longitudinal projections on each of said weight-strips en gaging said recesses in the corresponding side of said sash and means for keeping said projections and said recesses in engagement with each other, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 5th day of June, 1903.

GEORGE KABURECK.
